1 Application filed February 26, 1923. f SeriaI No. 621,2 1"). v '7 This invention relates'to a double'contact connecting socket adapted to receive an m candescent-lamp bulb in one end and an electrical contact plug in theother endl The object of the invention'is -to provide a cushion insert connection withinthefsocket of the most simple construction foryield locked in' position while'at the same-time making an electrical 1 connection therebe-- tween.

The main featureo'f the invention lies in the provision of a cyl ndrical socket havmg an electric cushion insert connection,

' removably placed therein formed Offl pair of insulating disks connected by' means of a spring which serves not only as anelectrica-l conductor, but asa resilient-cushion spring, the ends of said spring being secured to the disks by means of contact buttons or othersimilar means. This does away with a more elaborate and expensive construction commonly employed for obtraining the same results.

The fullnature of the invention will be' understood [from the accompanying drawings and the following *(IlBSCXlPlZlOll and claims.

In the drawings Fig. 1, illustrates a' socket'having a portion thereof shown in cross section. Fig. 2 is an enlarged central vertical section taken through the cushion insert .connection' Fig. 3 is an end elevation of the insert connection. Fig. 1 is the same as Fig. 2 showing a modified form.

Fig. 5 is an endelevation of .Fig. 4:. Fig. 6-"is the same as Fig. 2 showing a second modified form. Fig. 7 is an end elevation of Fig. 6. U

. In the drawings there 'is sh'ownthe usual type of cylindrical electric lamp socket 10 having bayonet slots lltherein for supporting the body12 of the lamp 18 in one end and the plug 1 1 in the. other end. The body 12 and the socket 14 are provided with the usual pins 15 for engaging in the bayonet slots 11, whereby they will be lockedtherein by the resilient spring pressure exerted againsttheir innerends.

not only to make electrical contact between the socket 14 and the lamp 123, but exert an outward pressure thereon for maintaining the pins 15 locked in the bayonet slots .11. Said coimectioncomprises a pair "of insulating washers or-di'sks 1 6 and 17 of such diameter as to sni'igly fit' within the cylinder 10. lhe disks areprovided with I central openings in which. are'secured the contact buttons 18 and 19 for engaging with and making electrical contact with the contactpoint 20 of the lamp 13and the contact 7 point of the plug, 14. Between .the disks.

otheiy-thereis provided a spiral compression spring 21 having one end in grippingflcon- 16Jand 1'7 and connecting them withaeachj tact about the; grooved neck portion 22 of the contact 18 andtheother endgri pped about the grooved contact l9.' f 1 1. By means of the above'construction it will be observed that the cushioninsert connecneck p0rtion23-of the tion may be formed separately from the socket and simply'spaced therein so as tof he between the lamp and the plug 1 L Uponthe'lamp and plug beingsecure'd in the ends'of thessocket they will engage the contact buttons 18and 19 and force them toward eachotheragainst the tension of the spring 21/ Thiswill hav elthe reverse effect of forcing the lamp and plug away from each other so as to cause the pins 15 to lock- 2 ton 18 and lamp 13, without the necessity oi embodyingan additional contact meanstherebetween. V

'In the form shown in Fig. 4.- the spring 121 has its ends inserted through diagonal] holes 122 formed in the. disks116 and 117 after which/the ends 118 and 119 of said spring are coiledso as'to lock the disks and spring together, and at the same'time serve as contact buttons in place of is the buttons 18 and 19. f I

' In the modified torm shown in-Fig.-6-the disks 216and 217 are provided with central openings through which the metal tubular "members 218-and 219 are inserted after having the ends of the spring 221 locked about their inner grooved ends 222. The ends bit. the members 218 and 219 may then be ham 'fmered so as to spread and lock the same within the disks, thereby forming contact buttons, as shown therein.

The invention claimed is ably e-in'ounted within said shell, and a=con-' tact spring positioned between said disks having the ends thereofso positioned as to make electrical contact with" said fixtures and yie'ldingly maintain said; disks in spaced relation, p p p r 2.
